In the springtime, blossoms fall
pink and white, yellow and purple—
like fat, flowery snowflakes—
each one different from the other.
In the summer, cold air collides with warm
causing thunderstorms. Lightning strikes
produce forest fires. Winds whip
and send ashes falling near and far.
In the autumn, leaves turn
yellow, red, and russet
and fall to the ground as surely
as their springtime cousins.
In the winter, the skies darken
and clouds release their moisture;
sometimes rain, sometimes snow,
but always falling to the earth.
Blossoms
Ash
Leaves
Snow
So could someone please explain
that with all of the downward vertical activity
why only one of these four seasons
is called fall?
